*Relapse frequency reduction was significantly greater in the Betaferon than in the Avonex group at six months (p<0.001), 12 and 18 months (p = 0.01), and 24 months (p = 0.02). The reduction was calculated on the actual basal relapse frequency in the patient subgroups at each time interval. | ||||||
No significant difference was found between Betaferon and Avonex groups in the proportion of relapse-free patients. | ||||||
